there is a bit of surface rust on the bores of an 18r block and i want to get the pistons out to assess the bore condiion
(beyond the obvious bits of rust of coourse) and replace the rings.
if i hammer from the bottom i am worried one of the pieces of rust may not flake off and will jam the piston and break a ring land. is there a way to get them out while beilng 100 percent certain nothing could go wrong.
i was going to go at it with 1200grit wet/dry but that still won't get close to the edge of the piston and the block bore where they meet. any methods?
oh and i tried removing the crank but i can't break the seal holding the rods in otherwise i was wondering if you could take the pistons out via the bottom.
